Anthony had been about to listen and actually leave.. until Tristan went on. It clicked then, why Tristan had attacked him on the train. Who would attack someone who made their brother happy, or had made their brother happy once upon a time? Yes, he had provoked the fight in the first place, but it had gotten worse after he told Taff he'd loved him. That's when the real anger had flared in Tristan. He was jealous of Anthony. "You do realize just how wrong that is, right? And you think that's supposed to make me jealous? You might not realize it, but he is your brother. I don't have those blood ties to him. And, fortunately for me, though, not so much for you, he isn't a perverted little fuck such as yourself." He blinked in finality of what he had said and turned around to head in another direction, probably not the best of ideas around someone like Tristan.
